• 16 Voices Drum Synthesizer and Stereo Sample Player • 2 oscillators (16 Waveforms) per voice with filters, Phase and Ring modulation • 1 sample player per voice with sample position, filters, phase and stereo control • Expressive instrument: velocity amount per Amp and Pitch modulation (MIDI CC) • Randomization engine (Drum Synthesizer, Sample Player, Envelopes) • Advanced Pitch and Amp envelopes with multi control points and delay • Envelope templates, modifiers and copy/paste • Mute/Choke groups: reduce overlapping and keep your drums tight • Drag and Drop File Support and multi sample loading • Mixer: 16 voices (Multi Output - If Supported By HOST) • Pad controller: voices triggered by Pad (MIDI OUT and Velocity Sensitive) • Includes classic drum machines built in presets for inspiration • Library explorer: drums organized by category • iOS AuV3 (iPad/iPhone) - Advanced Responsive Design, portrait and landscape views Everyone agrees that the drums are a very important key element of almost every genre out there, they are the foundation of a song. We are all fans of acoustic drums and drum machines, they each have different characters and strengths. FAC Drumkit combines both worlds, samples and synthesis, in order to provide new exciting and unique sounds. As a rule of thumb, the synthesizer section brings the body of the sound, and the sampler the unique character. Both parts are layered together and contain essential parameters to ensure they won't clash and will sit well together. On top of the samples and synthesizer section, FAC Drumkit brings unique Amp and Pitch envelopes with precise control points to modify the curve in a gentle or extreme way. The envelopes play a very important part in the signal path because, thanks to their flexibility, they allow designing very special transition. Indeed, the envelope of a Clap is probably the best one to illustrate the benefit of such envelopes created with points. The burst kind of sound is very hard to replicate with classic ADSR, it's not the case in FAC Drumkit. Needless to say, thanks to the control points the pitch transitions are also more interesting and precise. The value of each control point can also be altered manually, to set the root note of a kick for example. FAC Drumkit is for everyone, as sound designer you will be able to synthesize your own drums in a fun and creative way. On the other hand, if you are looking for instant results, use the provided presets or load your favourite sample pack in the sample section of the 16 voices. The randomization engine makes the creation of new sounds really easy. Define what you want to randomize and you are ready to go. Remember that instrument category plays a role in the randomization process. For example, if you want to design a drum kick set the instrument label to BD (or use the voice index to get a wider sound palette). It's also very interesting to select a sound you like and start the randomization process from there, in a gentle way or not, thanks to the options available in the voice button (page selector). FAC Drumkit is an expressive instrument, the amount of velocity can be set individually for each amplitude envelope, and the pitch envelopes can be modulated by external MIDI control change messages. The pitch modulation applies on control points or on the whole pitch envelopes. Important: The standalone app is a factory version only and you won't be able to save user presets. Use the AuV3.

Euclidean Sequencer is an alternative incarnation of the classic step sequencer that has become very popular in the modular realm. It is based on Euclidean rhythms developed by computer scientist Godfried Toussaint in 2004. Euclidean rhythms have their roots in Greek mathematician Euclid’s algorithm, which involves using the greatest common divisor of two numbers to place hits in a sequence as evenly as possible across a set timing divisions. In practice this is actually simpler than you might think, and Euclidean Sequencer is a great way to auto generate complex musical sequences with no prior knowledge of how it actually works. Euclidean Sequencer is an AUv3 plugin that can be loaded inside any popular host application that has flexible MIDI routing. You can define up to 4 Euclidean rhythm parts, each part is referred to as a band. The bands are labelled A-D and colour coded RED, ORANGE, GREEN and CYAN. Together these 4 bands create a pattern, and you can create up to 16 seperate patterns per song patch. Since each band can specify its own note sequence and output MIDI channel, you can create some quite sophisticated rythms patterns, driving 4 seperate instruments at once. Even better you can seamlessly switch patterns to create even longer evolving sequences. Patterns follow a specified key, scale, or defined chord. You can even use MIDI input to automatically make note sequences conform to the currently playing chords. Please note: This is an AUv3 plugin instended to be used inside your favourite host DAW such as AUM, Cubasis, Loopy Pro etc. It will work with any app that has flexible MIDI routing. This app is not compatible with GarageBand as it doesn't support MIDI plugins. Features 4 Band Sequencer 16 Patterns per patch. Up to 64 events per band. Seamless pattern transitions. Output Port and Channel control. Per Band and Global speeds. Randomize function with varying complexity. Supports note Probability. Reverse and PingPong modes. MIDI Chord recognition. Latch mode. 4 Band Velocity Mixer Controller support. Gate Mode. AUv3 Compatible.
